?Accelerating a charged particle

An accelerated charged particle emits radiation with respect to a stationary observer but if the observer is accelerated along with the particle does the observer still detect the particle emitting radiation?. Suppose we put a detector in the G machine at NASA and get it up to say 12G's would it detect radiation coming from the matter it is mounted on? I don't think so and if it doesn't that means radiating particles obey the laws of general relativity which I find extremely interesting.

Ok, how about say a million G's? That should produce some detectable radiation. BTW, our G machine is in outer space millions of kilometers from any matter. Now if we have a detector just outside the arc of the machine that transmits it's readings to us it will detect radiation coming from the machine but I don't believe the detector on the machine will detect radiation except from our nearby detector which would appear to be accelerating to the detector on the machine.

By a G machine I assume you are thinking of an electromagnetic accelerator?And as that EM field interact with your particle (electron f.ex) sure, you will have an radiation. What you're not asking, if so, is if the electron would radiate if being in a 'free fall' toward f.ex a Black Hole. Or was it this you meant after all?

How exactly would that electron free falling towards the BH be able to radiate?Tell me Ron because I don't know?==You will have an acceleration there too, as seen from an observer.

The G machine at NASA used to test Astronauts in high G conditions. My point is that an accelerated charged particle emits radiation relative to an observer. If the observer is accelerated along with the particle then the observer does not detect radiation being emitted by the particle. If that is true, and I have no way knowing if it is true, it should be telling us something important.

There is no need for normal rotating machines which are far too slow and weak to produce significant radiation.

We observe radiation from accelerated particles all the time. The most common form is in the form of heat it is the accelerations of the particles as they collide that produces the heat radiation with which we are all familiar. particle velocities at room temperature are typically thousands of miles an hour and interaction times to reverse this in a collision about the size of one atom extremely short so accelerations are truly enormous.

Radiation can be produced in a more controlled way using particles confined in orbits by magnetic fields. This is called synchrotron radiation and some of the most powerful x ray sources use this sort of radiation and there are several research facilities all over the world.

synchrotron radiation can also be observed in the earth's ionosphere and in outer space at all sorts do frequencies from radio to light.

a gravitational field could also provide the orbital confinement and it is probably a significant part of quasar radiation.

An accelerating charged particle in a gravitational field should radiate but in general this radiation will not be observed because of the way in which the particles will in general be arranged and interact with the fields.

A lot of space is filled with charged particles moving under gravity and electromagnetism. This can be seen very well in observations of the sun.

A plasma contains equal quantities of positive (usually protons or other nuclei) and negatively charged (usually electrons) particles now the motions and resonances of protons and electrons in a magnetic field are very different because they have different masses. they therefore behave differently and their effects are different. However the motion of particles under gravity does not depend on their mass at all heavy and light particle tend to fall at the same rate so the radiation effects are equal and opposite on plasma falling freely or in orbit under gravity and nothing else.

The critical difference comes when turbulence and viscosity sets in and this allows the generation of magnetic effects
